The purpose of the Inventory Balance Report (IBR) is to show the value of inventory on hand at each month end period. You can print it in summary or by FIFO layer.
The report is driven solely by the INVENTORY_BALANCE table which is updated by the cost utilities.
If you’re in a STANDARD COSTING environment then the IBR really does not serve a purpose. Basically, the inventory balance for any given month is the quantity on hand x the total unit standard cost in effect at that time.
Unfortunately the INVENTORY_BALANCE table in a FIFO database eventually closes FIFO layers off and they are removed from the table for the next period. In a standard cost database this never occurs and the table continues to grow. At one of our client more than 50GB (yes GB with a G!) of the database was in the inventory balance table and it was providing no benefit what so ever. The table was truncated and guess what…costing performance improved dramatically, especially for the first run of the month when this table is updated for the new period.
If you are standard cost consider truncating the data from the INVENTORY_BALANCE table.
